Then every time we add a function, or anything else, we can bikeshed about whether it should go in pg_catalog or pg_extra! FWIW, EnterpriseDB has something like this for Advanced Server, and it actually adds a fair amount of complexity, much of it around OverrideSearchPath. It's not unmanageable, but it's not trivial, either. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
